If theatre were a religion, explains David Mamet in his opening chapter, "many of the observations and suggestions in this book might be heretical. " As always, Mamet delivers on his promise: in "Theatre, " the acclaimed author of "Glengarry Glen Ross" and "Speed the Plow "calls for nothing less than the death of the director and the end of acting theory. For Mamet, either actors are good or they are non-actors, and good actors generally work best without the interference of a director, however well-intentioned. Issue plays, political correctness, method actors, impossible directions, Stanislavksy, and elitists all fall under Mamet's critical gaze. To students, teachers, and directors who crave a blast of fresh air in a world that can be insular and fearful of change, "Theatre" throws down a gauntlet that challenges everyone to do better, including Mamet himself.
